Should I choose ARMA Supercharger or not?

[yesido]

Hi there, I'm very new to here.

Recently, I considered to hoist up my 120i. It seems that very few company produce the s/c kits for our N46 engine. Then I come here and find ARMA. A bit tempting to choose it to boost my bimmer. But probably still some issues in their products. (the thread in 3-series forum) And very few threads speaking of them.

Are there any factors I should take into account or prepare in advance? (except price! LOL)

I haven't done any mods to my 120i. Or What do you guys think is the best bolt on mod for more power without voiding the warranty?

Maybe someone will suggest directly to go for 135i, but I think tuning will be another world where I can get more fun.

you can tune a 135... i dont see the point in buying a base model econobox then trying to get performance from it...

just want to make my daily driving more smoothly

Thanks vid~

Waiting my car over warranty...

I'll try it.

Wouldn't it be cheaper to just trade your 128 for a 135?

[AlwayzUnce]

id like to try this down the road... ill look into it when the time is right

[bimmerlike]

There are more information in e90post. Here is few 1er know ARMA...

Its like 8k. Well built but thats alot of money.

Doesn't look like it does much better than that 325i. I'd say put the 8k into a faster car. You can get a lot more out of a Japanese car with the same amount of money, if all you're looking for is power/straight line acceleration..

Why on earth would you not just trade for a 135i?

I would have went with the 135i for my weekend car, but after doing research and seeing all the problems the 135i has, I decided to get a new 370z and twin turbo it. I'm making more horsepower/ torque than any 135i I have seen on here so far and it has been very reliable with zero issues so far. Not that all the 135i's are going to have the same problems, but it seems for the most part, there's still major issues with the 135i. Also, the 128i is a AWESOME autocross/ track car with the right suspension and you could only benefit from adding a little more power.

I went from a 370z to the 135 and have to say, I can totally understand why you would do that for a "weekend" car. The 370z was awesome but kind of hard to live with day-to-day. The VQ37 does not know what torque is, but I can't imagine what a beast it must be with a TT kit...damn. The car handled SO GOOD, but had some definite brake/oil issues. Do you have trouble keeping oil temps in check with the turbos or did you put on a big oil cooler? Ahh I loved that car though...with R-Comps and about 320 rwhp I was making Z06's let me pass on the track

THAT being said...still do not understand why you would spend over 6k on a SC kit for a 128. Any suspension stuff you do to it you could also do to a 135i...and you're never going to get the power from a 128 you could from the 135 for anywhere near the cost...

I had to go with a bigger oil cooler, because as you know, the 370z engine gets really hot during track runs. I never had brake boil yet though as some people have maybe because I have the factory Brembo's. The car is amazing with the TT and tune from Forged Performance. I haven't encountered anything on the street that can hang yet, but I'm sure my day is coming, especially in Atlanta. You never know what car is about to pounce on you around there. LOL

I had the factory Akebono's (is that what you meant by brembos?) which were great stopping wise once you replaced the brake pads, but they just don't stay cool on the track under stock power. I can't imagine with over 5 or 6 hundred horsepower how quickly they are going to overheat.

Cause I don't live in a big country, the displacement of 120 is more suitable for me.
